(S)-2-Methoxy-3-phenylpropanoic acid (Compounds 7a, 0.50 g, 2.50 mmol) and 2-bromoacetonitrile (1.20 g, 10.00 mmol) were dissolved in acetonitrile (60 ml). Then triethylamine (0.50 g, 4.99 mmol) was added dropwise under ice-cooling. After stirring at room temperature for 40 minutes, the reaction solution was concentrated under reduced pressure, and the residue was purified by column chromatography (petroleum ether:ethyl acetate=20:1) to afford the title compound (0.39 g, 65%).
